Zpeech (http://zpeech.com/) has put itself on sale on eBay. The service was self-funded, but the developers moved on to Guut.de and other projects, so they “are selling zpeech.com now, because we believe in the idea of a widget for the freedom of zpeech on any website and want to see our baby grow in good and strong hands,” see the auction details
The idea of Zpeech is to let people chat or discuss any website on the website itself, but users needed to prefix any URL with zpeech.com/ for their widget to pop up – which is a bit cumbersome and the web is a big place so the chances of serendipically running into an interesting conversation on random pages are low.
Recent eBay exits in Germany include Twitter clone dukudu which sold for €43K a few weeks back, texteln, another Twitter clone, went for 11K and if you remember this week brokr was purchased for 75K.
update: Zpeech has shut down
